The Proposed Specifiers for Conduct Disorder - Parent (PSCD-P): Convergent Validity, Incremental Validity, and...

Area of Science:

• Child and Adolescent Psychology
• Developmental Psychopathology
• Forensic Psychology

Background:

• Youth psychopathy involves interpersonal, affective, lifestyle, and antisocial impairments.
• Prior research on Conduct Disorder (CD) primarily focuses on callous-unemotional (CU) traits, limiting understanding of a multi-component approach.
• The Proposed Specifiers for Conduct Disorder (PSCD) assesses grandiose-manipulative (GM), CU, and daring-impulsive (DI) features alongside CD symptoms.

Purpose of the Study:

• To test the psychometric properties of the parent-report version of the PSCD (PSCD-P).
• To determine if a multi-component assessment of psychopathic traits (GM, CU, DI) incrementally predicts outcomes related to CD compared to a CU-only approach.
• To examine the validity of the PSCD-P in assessing adolescent interpersonal functioning.

Main Methods:

• Utilized a mixed clinical/community sample of 134 adolescents (mean age = 14.49).
• Administered parent-report measures, including the PSCD-P, and collected data on parent-adolescent conflict.
• Employed independent observers to rate adolescents' behavioral reactions during simulated social interactions.

Main Results:

• Confirmatory factor analyses supported a 19-item PSCD-P with acceptable reliability and a bifactor solution (GM, CU, DI, CD factors).
• PSCD-P scores demonstrated incremental validity in predicting parent-adolescent conflict.
• PSCD-P scores also predicted observer-rated behavioral reactions in simulated social interactions.

Conclusions:

• The PSCD-P is a psychometrically sound measure for assessing multi-component psychopathy in adolescents.
• A multi-component approach to psychopathy, as measured by the PSCD-P, provides incremental information about CD-related outcomes beyond CU traits alone.
• Findings support the utility of the PSCD for understanding adolescent interpersonal functioning and have implications for future research and clinical practice.
